Physically Unclonable Functions (PUFs) have been a potent choice for enabling low-cost, secure communication. However, in most applications, one party holds the PUF, and the other securely stores the challenge-response pairs (CRPs).
It does not remove the need for secure storage entirely, which is one of the goals of PUFs.
This paper proposes a PUF-based …
